Teamviewer 12 no GUI

Question

I've been using teamviewer on Ubuntu for a long time. Since I upgraded to version 12 it works ok for a couple of days, sometimes weeks and then suddenly it stops launching. I've managed at least three times to get it to work again uninstalling it an then removing every trace of it using locate command. This time that didn't work niether. The package is Teamviewer_12.0.71510_i386.deb running on Ubuntu 16.04 x64, the same package was used successfully before. The log on /var/log/teamviewer12 is:

Solution

Same problem, I solved in this way, looking at /home/user/.config/teamviewer/client.conf the parameter [strng] FT_Start_Directories = "" was ridiculously long and I simply deleted anything between the " " as many of the directories were not even in my computer. Now Teamviewer is back!

Same problem! I already purged and reinstalled several times, it works for some days and then the problem comes back.. Did you find any solution?

[Roni Berezin]

Actually, the folders that appear as parameters in the string you mention, are folders located in computers I've connected and shared files with. This means that the problem is caused when you share files with other computers.

Yes it's the same for me.. Should be a TW bug..

[Russel FP]

Yes, the same here, as @RoniBerezin mentioned I had some path from last file sharing with other computer.
